Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Neal Norwitz92422fb2006-08-18 03:57:54 +000010*Release date: XX-XXX-200X*
11
12Core and builtins
13-----------------
14
Collin Winter62903052007-05-18 23:11:24 +000015- except clauses may now be spelled either "except E, target:" or
16 "except E as target:". This is to provide forwards compatibility with
17 Python 3.0.
18
Brett Cannon229cee22007-05-05 01:34:02 +000019- Deprecate BaseException.message as per PEP 352.
20
Armin Rigo9790a272007-05-02 19:23:31 +000021- Bug #1303614: don't expose object's __dict__ when the dict is
22 inherited from a builtin base.
23
Vinay Sajip8549ce32007-05-06 17:53:37 +000024- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000025 setting a plain string, ie don't expand to single letter identifiers.
26
Raymond Hettinger13936692007-04-11 18:40:58 +000027- Request #1191699: Slices can now be pickled.
28
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000029- Request #1193128: str.translate() now allows a None argument for
30 translations that only remove characters without re-mapping the
31 remaining characters.
32
Georg Brandl5cb76c12007-03-21 09:00:39 +000033- Patch #1682205: a TypeError while unpacking an iterable is no longer
34 masked by a generic one with the message "unpack non-sequence".
35
Neal Norwitzaa754b72007-03-21 06:39:48 +000036- Remove unused file Python/fmod.c.
37
Guido van Rossum143b5642007-03-23 04:58:42 +000038- Bug #1683368: The object.__init__() and object.__new__() methods are
39 now stricter in rejecting excess arguments. The only time when
40 either allows excess arguments is when it is not overridden and the
41 other one is. For backwards compatibility, when both are
42 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000043 warning later). Also, type.__init__() insists on the same signature
44 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000045
Georg Brandl2b869942007-03-17 16:08:45 +000046- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
47 to complex using its __complex__() method before falling back to the
48 __float__() method. Therefore, the functions in the cmath module now
49 can operate on objects that define a __complex__() method.
50
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000051- Patch #1623563: allow __class__ assignment for classes with __slots__.
52 The old and the new class are still required to have the same slot names.
53
Collin Winter77c67bd2007-03-16 04:11:30 +000054- Patch #1642547: Fix an error/crash when encountering syntax errors in
55 complex if statements.
56
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000057- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
58 is called with an object that is faking its type.
59
Žiga Seilnacht71436f02007-03-14 12:24:09 +000060- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
61 name.
62
Georg Brandl5240d742007-03-13 20:46:32 +000063- Patch #1444529: the builtin compile() now accepts keyword arguments.
64
Georg Brandl7b9c5552007-03-12 14:30:05 +000065- Bug #1678647: write a newline after printing an exception in any
66 case, even when converting the value to a string failed.
67
Georg Brandl871f1bc2007-03-12 13:17:36 +000068- The dir() function has been extended to call the __dir__() method on
69 its argument, if it exists. If not, it will work like before. This allows
70 customizing the output of dir() in the presence of a __getattr__().
71
Collin Winter276887b2007-03-12 16:11:39 +000072- Patch #922167: Python no longer segfaults when faced with infinitely
73 self-recursive reload() calls (as reported by bug #742342).
74
Žiga Seilnacht89032082007-03-11 15:54:54 +000075- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
76
Collin Wintere38051d2007-03-09 20:33:07 +000077- Patch #1491866: change the complex() constructor to allow parthensized
78 forms. This means complex(repr(x)) now works instead of raising a
79 ValueError.
80
Georg Brandlaa2321b2007-03-07 00:40:28 +000081- Patch #703779: unset __file__ in __main__ after running a file. This
82 makes the filenames the warning module prints much more sensible when
83 a PYTHONSTARTUP file is used.
84
Georg Brandl49aafc92007-03-07 00:34:46 +000085- Variant of patch #697613: don't exit the interpreter on a SystemExit
86 exception if the -i command line option or PYTHONINSPECT environment
87 variable is given, but break into the interactive interpreter just like
88 on other exceptions or normal program exit.
89
Georg Brandl00cd8182007-03-06 18:41:12 +000090- Patch #1638879: don't accept strings with embedded NUL bytes in long().
91
Georg Brandl098cd692007-03-06 12:17:50 +000092- Bug #1674503: close the file opened by execfile() in an error condition.
93
Georg Brandl0fca97a2007-03-05 22:28:08 +000094- Patch #1674228: when assigning a slice (old-style), check for the
95 sq_ass_slice instead of the sq_slice slot.
96
Neal Norwitz88516a62007-02-26 22:41:45 +000097- When printing an unraisable error, don't print exceptions. before the name.
98 This duplicates the behavior whening normally printing exceptions.
99
Martin v. Löwisfd963262007-02-09 12:19:32 +0000100- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
101
Brett Cannon129bd522007-01-30 21:34:36 +0000102- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
103 catch a string exception raises DeprecationWarning.
104
Brett Cannonf5bee302007-01-23 23:21:22 +0000105- Bug #1377858: Fix the segfaulting of the interpreter when an object created
106 a weakref on itself during a __del__ call for new-style classes (classic
107 classes still have the bug).
108
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000109- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
110 frame's thread state.
111
Thomas Wouters6ed19652007-01-23 13:50:49 +0000112- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py

115
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000116- Prevent seg fault on shutdown which could occur if an object
117 raised a warning.
118
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000119- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
120 to avoid relying on atexit.
121

Georg Brandlb9f4ad32006-10-29 18:31:42 +0000133- Bug #1576657: when setting a KeyError for a tuple key, make sure that
134 the tuple isn't used as the "exception arguments tuple".
135

139 again, no longer the posix error code.
140
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000141- Patch #1549049: Support long values in structmember, issue warnings
142 if the assigned value for structmember fields gets truncated.
143
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000144- Update the peephole optimizer to remove more dead code (jumps after returns)
145 and inline unconditional jumps to returns.
146
Georg Brandl2c1375c2006-10-12 11:27:59 +0000147- Bug #1545497: when given an explicit base, int() did ignore NULs

149
Georg Brandl846f73a2006-10-08 07:11:54 +0000150- Bug #1569998: break inside a try statement (outside a loop) is now
151 recognized and rejected.
152
Armin Rigo7ccbca92006-10-04 12:17:45 +0000153- list.pop(x) accepts any object x following the __index__ protocol.
154
155- Fix some leftovers from the conversion from int to Py_ssize_t
156 (relevant to strings and sequences of more than 2**31 items).
157
158- A number of places, including integer negation and absolute value,
159 were fixed to not rely on undefined behaviour of the C compiler
160 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000161
Georg Brandl3267d282006-09-30 09:03:42 +0000162- Bug #1566800: make sure that EnvironmentError can be called with any

178
Brett Cannon9adeab72006-09-20 18:34:28 +0000179- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

181
Georg Brandlec6c2df2006-09-11 09:38:35 +0000182- Make _PyGILState_NoteThreadState() static, it was not used anywhere

201
Neal Norwitzdac090d2006-09-05 03:53:08 +0000202- Bug #1520864: unpacking singleton tuples in list comprehensions and
203 generator expressions (x for x, in ... ) works again. Fixing this problem

219
Neal Norwitze0e70a42007-05-16 05:06:33 +0000220- Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in

222
Georg Brandla09a96a2007-05-15 20:19:34 +0000223- HTML-escape the plain traceback in cgitb's HTML output, to prevent

239
Georg Brandlfb4b3b72007-04-24 15:27:13 +0000240- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
241 (as opposed to the command line) will now write file names ending in
242 ".cpp" too.
243
Facundo Batistad918a652007-04-24 13:54:38 +0000244- As specified in RFC 2616, an HTTP response like 2xx indicates that
245 the client's request was successfully received, understood, and accepted.
246 Now in these cases no error is raised in urllib2.
247
Brett Cannonc6906652007-04-01 18:47:27 +0000248- Bug #1290505: time.strptime's internal cache of locale information is now

256 closes patch #723312.
257
Vinay Sajip8549ce32007-05-06 17:53:37 +0000258- Patch #1676823: Added create_connection() to socket.py, which may be
259 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista07c78be2007-03-23 18:54:07 +0000260 now accepts an optional timeout).
261
Martin v. Löwis0af33882007-03-23 13:27:15 +0000262- Bug #978833: Revert r50844, as it broke _socketobject.dup.
263
Žiga Seilnacht7492e422007-03-21 20:07:56 +0000264- Bug #1675967: re patterns pickled with Python 2.4 and earlier can

292 the debugged script, which means that imports from __main__ work
293 correctly now.

365 and TestSuite subclasses (not instances) are no longer accepted in
366 TestSuite.addTest(). This should cause no incompatibility since it

399 import semantics.

892Core and builtins
893-----------------
894
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000895- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000896 compared equal or unequal to a string and a UnicodeDecodeError
897 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000898
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000899 Instead, the equal (==) and unequal (!=) comparison operators will
900 now issue a UnicodeWarning and interpret the two objects as
901 unequal. The UnicodeWarning can be filtered as desired using
902 the warning framework, e.g. silenced completely, turned into an
903 exception, logged, etc.
904
905 Note that compare operators other than equal and unequal will still
906 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000907
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000908- Fix segfault when doing string formatting on subclasses of long.
909
910- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
911 with new-style classes.
912
913- Fix bug related to __len__ functions returning negative values with
914 classic classes.
915
916- Patch #1538606, Fix __index__() clipping. There were some problems
917 discovered with the API and how integers that didn't fit into Py_ssize_t
918 were handled. This patch attempts to provide enough alternatives
919 to effectively use __index__.
920
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000921- Bug #1536021: __hash__ may now return long int; the final hash
922 value is obtained by invoking hash on the long int.
923
Thomas Hellerab1049c2006-08-08 17:37:00 +0000924- Bug #1536786: buffer comparison could emit a RuntimeWarning.
925
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000926- Bug #1535165: fixed a segfault in input() and raw_input() when
927 sys.stdin is closed.
928
Thomas Heller74d36f02006-08-04 18:17:40 +0000929- On Windows, the PyErr_Warn function is now exported from
930 the Python dll again.
931
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000932- Bug #1191458: tracing over for loops now produces a line event
933 on each iteration. Fixing this problem required changing the .pyc
934 magic number. This means that .pyc files generated before 2.5c1
935 will be regenerated.
936
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000937- Bug #1333982: string/number constants were inappropriately stored
938 in the byte code and co_consts even if they were not used, ie
939 immediately popped off the stack.
940
Georg Brandle9462c72006-08-04 18:03:37 +0000941- Fixed a reference-counting problem in property().
942
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000943
944Library
945-------
946
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000947- Fix a bug in the ``compiler`` package that caused invalid code to be
948 generated for generator expressions.
949
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000950- The distutils version has been changed to 2.5.0. The change to
951 keep it programmatically in sync with the Python version running
952 the code (introduced in 2.5b3) has been reverted. It will continue
953 to be maintained manually as static string literal.
954
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000955- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000956 and this cannot be converted to the required C type, an exception is
957 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000958 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000959
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000960- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000961 an exception.
962
Tim Petersc10c9d02006-09-05 02:18:09 +0000963- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000964 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000965 workarounds for clocks with low resolution, to stop the code yielding
966 duplicate UUIDs.
967
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000968- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
969 before raising SystemExit, allowing IDLE to honor quit() and exit().
970
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000971- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
972
Georg Brandl7a1af772006-08-14 21:55:28 +0000973- Patch #1536071: trace.py should now find the full module name of a
974 file correctly even on Windows.
975
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000976- logging's atexit hook now runs even if the rest of the module has
977 already been cleaned up.
978
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000979- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000980
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000981- Bug #1531405, format_exception no longer raises an exception if
982 str(exception) raised an exception.
983
Neil Schemenauer06ded092006-08-04 16:20:30 +0000984- Fix a bug in the ``compiler`` package that caused invalid code to be
985 generated for nested functions.
986
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000987

990
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000991- Patch #1511317: don't crash on invalid hostname (alias) info.
992
Georg Brandl3335a7a2006-08-14 21:42:55 +0000993- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
994 raises the correct exceptions.
995
Thomas Heller1ce433e2006-08-14 16:20:04 +0000996- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
997 '-no-stack-protector' compiler flag for OpenBSD has been removed.
998
Thomas Heller86720042006-08-14 11:17:48 +0000999- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1000 uses the _as_parameter_ attribute when objects are passed to foreign
1001 function calls. The ctypes version number was changed to 1.0.1.
1002
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001003- Bug #1530559, struct.pack raises TypeError where it used to convert.
1004 Passing float arguments to struct.pack when integers are expected
1005 now triggers a DeprecationWarning.
1006
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001007

1026
1027
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001028Build
1029-----
1030
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001031- Bug #1535502, build _hashlib on Windows, and use masm assembler
1032 code in OpenSSL.
1033
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001034- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1040-----
1041
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001042- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1043
Tim Peters4643c2f2006-08-10 22:45:34 +00001044- Bug #1069160. Internal correctness changes were made to
1045 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1046 the documentation was changed to state that the return value
1047 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001050What's New in Python 2.5 beta 3?
1051================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001052
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001053*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001054
1055Core and builtins
1056-----------------
1057
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001058- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001059 returned a long (see PEP 353).
1060
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001061- Bug #1515471: string.replace() accepts character buffers again.
1062
Neal Norwitz07aadb12006-07-30 06:55:48 +00001063- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1064 This provides the proper warning for struct.pack().
1065 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1066
Neal Norwitz0d62a062006-07-30 06:53:31 +00001067- Patch #1531113: Fix augmented assignment with yield expressions.
1068 Also fix a SystemError when trying to assign to yield expressions.
1069
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001070- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1071 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1072 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1073 excessive filesystem operations during imports.
1074
Tim Petersbc24eee2006-07-27 01:14:53 +00001075- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1076 operations on signed longs that are formally undefined by C.
1077 Unfortunately, at least one compiler now cares about that, so complicated
1078 the code to make that compiler happy again.
1079
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001080- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1081
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001082- Patch #1232023: Stop including current directory in search
1083 path on Windows.
1084
Neal Norwitze1fdb322006-07-21 05:32:28 +00001085- Fix some potential crashes found with failmalloc.
1086
Neal Norwitze7563102006-07-17 01:00:16 +00001087- Fix warnings reported by Klocwork's static analysis tool.
1088
Neal Norwitz84be93b2006-07-16 01:50:38 +00001089- Bug #1512814, Fix incorrect lineno's when code within a function
1090 had more than 255 blank lines.
1091
Georg Brandl9dceedb2006-07-12 15:31:17 +00001092- Patch #1521179: Python now accepts the standard options ``--help`` and
1093 ``--version`` as well as ``/?`` on Windows.
1094
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001095- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001096 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001097 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001098
Tim Peters112aad32006-07-19 00:03:19 +00001099- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001100 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001101 new ``sys._current_frames()`` returns a dictionary with one entry,
1102 mapping the faux "thread id" 0 to the current frame.
1103
Ronald Oussoren3075e162006-07-25 20:28:55 +00001104- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001105
Ronald Oussoren3075e162006-07-25 20:28:55 +00001106
Neal Norwitza1f10902006-07-12 07:28:29 +00001107Library
1108-------
1109
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001110- Correction of patch #1455898: In the mbcs decoder, set final=False
1111 for stream decoder, but final=True for the decode function.
1112
Georg Brandl07fec3a2006-08-01 18:49:24 +00001113- os.urandom no longer masks unrelated exceptions like SystemExit or
1114 KeyboardInterrupt.
1115
Tim Peters4643c2f2006-08-10 22:45:34 +00001116- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001117 shutil.copytree on Windows
1118
Georg Brandle34ac7c2006-07-30 11:07:23 +00001119- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1120 refers to file descriptors, not file objects.
1121
Tim Petersc10c9d02006-09-05 02:18:09 +00001122- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001123 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001124 #1513611, and probably others.
1125
Georg Brandledd9b0d2006-07-29 09:33:26 +00001126- Bug #1441397: The compiler module now recognizes module and function
1127 docstrings correctly as it did in Python 2.4.
1128
Tim Peters6f681472006-07-27 23:44:37 +00001129- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1130 lost that tests are sorted by name before being run. This rarely
1131 matters for well-written tests, but can create baffling symptoms if
1132 side effects from one test to the next affect outcomes. ``DocTestFinder``
1133 has been changed to sort the list of tests it returns.
1134
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001135- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001136 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001137
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001138- Bug #978833: Really close underlying socket in _socketobject.close.
1139
Georg Brandl8c036cc2006-08-20 13:15:39 +00001140- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1141 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001142
Georg Brandlcf0c1722006-07-26 07:23:32 +00001143- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1144 to recursive calls and call it with the failing package name.
1145
Martin v. Löwis0b483032006-07-25 09:53:12 +00001146- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1147
Georg Brandlc13c34c2006-07-24 14:09:56 +00001148- Patch #1515343: Fix printing of deprecated string exceptions with a
1149 value in the traceback module.
1150
Greg Ward48fae7a2006-07-23 16:05:51 +00001151- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1152
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001153- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1154
Brett Cannoncaebe222006-07-18 04:41:36 +00001155- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1156 argument tuple. For arguments where zero is illegal, the value is forced to
1157 the minimum value that is correct. This is to support an undocumented but
1158 common way people used to fill in inconsequential information in the time
1159 tuple pre-2.4.
1160
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001161- Patch #1220874: Update the binhex module for Mach-O.
1162
Barry Warsawb110bad2006-07-21 14:51:07 +00001163- The email package has improved RFC 2231 support, specifically for
1164 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1165 (name*0=<blah>) parameter continuations. This may change the types of
1166 values returned from email.message.Message.get_param() and friends.
1167 Specifically in some cases where non-encoded continuations were used,
1168 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1169 will just return the string (since non-encoded continuations don't have
1170 charset and language parts).
1171
1172 Also, whereas % values were decoded in all parameter continuations, they are
1173 now only decoded in encoded parameter parts.
1174
Ronald Oussoren3075e162006-07-25 20:28:55 +00001175- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1176
1177- Bug #1517996: IDLE now longer shows the default Tk menu when a
1178 path browser, class browser or debugger is the frontmost window on MacOS X
1179
Barry Warsaw00decd72006-07-27 23:43:15 +00001180- Patch #1520294: Support for getset and member descriptors in types.py,
1181 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1182 of an object against these built-in types and more importantly, for getting
1183 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001186Extension Modules
1187-----------------
1188
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001189- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1190 a socket operation on a socket with a timeout, the exception will be
1191 caught correctly. Previously, the exception was not caught.
1192
Thomas Heller1393d6a2006-07-28 21:43:20 +00001193- Patch #1529514: The _ctypes extension is now compiled on more
1194 openbsd target platforms.
1195
Tim Peters9cab5932006-07-28 00:30:00 +00001196- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1197 a memory leak, affecting pickles and deep copies.
1198
Tim Petersbc24eee2006-07-27 01:14:53 +00001199- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1203
Thomas Hellerce049a02006-07-14 17:51:14 +00001204- Patch #1521817: Index range checking on ctypes arrays containing
1205 exactly one element enabled again. This allows iterating over these
1206 arrays, without the need to check the array size before.
1207
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001208- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001209 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001210 /dev/null in certain cases; this is now fixed.
1211
Thomas Heller47d7a062006-07-12 08:43:47 +00001212- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1213 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001214
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001215- Because of a misspelled preprocessor symbol, ctypes was always
1216 compiled without thread support; this is now fixed.
1217
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001218- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1219 methods now allow their database parameter to be None as the
1220 sleepycat API allows.
1221
Matt Flemingec926502006-07-28 11:27:27 +00001222- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1223 bluetooth API compared with Linux and FreeBSD.
1224
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001225Tests
1226-----
1227
1228- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1229 how long the test file should take to play. Now accepts taking 2.93 secs
1230 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1231
Georg Brandl4793aa32006-07-28 18:31:39 +00001232- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1233 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1234 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001235
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001236Build
1237-----
1238
1239- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1240
Ronald Oussoren26cad082006-08-01 21:00:57 +00001241Mac
1242---
1243
1244- PythonLauncher now works correctly when the path to the script contains
1245 characters that are treated specially by the shell (such as quotes).
1246
1247- Bug #1527397: PythonLauncher now launches scripts with the working directory
1248 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001249 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001250 expect.

1258Core and builtins
1259-----------------
1260
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001261- Bug #1441486: The literal representation of -(sys.maxint - 1)
1262 again evaluates to a int object, not a long.
1263
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001264- Bug #1501934: The scope of global variables that are locally assigned
1265 using augmented assignment is now correctly determined.
1266
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001267- Bug #927248: Recursive method-wrapper objects can now safely
1268 be released.
1269
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001270- Bug #1417699: Reject locale-specific decimal point in float()
1271 and atof().
1272
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001273- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1274 omit a default "error" argument for NULL pointer. This allows
1275 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001276
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001277- Bug #1519018: 'as' is now validated properly in import statements.
1278
Neal Norwitz28746ab2006-07-09 22:14:42 +00001279- On 64 bit systems, int literals that use less than 64 bits are
1280 now ints rather than longs.
1281
Neal Norwitzed657552006-07-10 00:04:44 +00001282- Bug #1512814, Fix incorrect lineno's when code at module scope
1283 started after line 256.
1284
Tim Peters32a83612006-07-10 21:08:24 +00001285- New function ``sys._current_frames()`` returns a dict mapping thread
1286 id to topmost thread stack frame. This is for expert use, and is
1287 especially useful for debugging application deadlocks. The functionality
1288 was previously available in Fazal Majid's ``threadframe`` extension
1289 module, but it wasn't possible to do this in a wholly threadsafe way from
1290 an extension.
1291

1299
Tim Peters32a83612006-07-10 21:08:24 +00001300- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001301 environment variable to be set in order to the SDK environment
1302 for finding the compiler, include files, etc.

1307
Thomas Woutersadd19112006-07-05 11:03:49 +00001308- string.Template() now correctly handles tuple-values. Previously,
1309 multi-value tuples would raise an exception and single-value tuples would
1310 be treated as the value they contain, instead.
1311
Martin v. Löwisede77f52006-07-03 13:01:35 +00001312- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1319 degrees and radians.
1320
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001321- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001322 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001323
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001324- Bug #1514703: Only setup canvas window in turtle when the canvas

1331 attribute values.
1332
1333- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1334 sgmllib ('[' and ']' were not accepted).
1335
Georg Brandl1be63af2006-06-28 20:23:25 +00001336- Fix a bug in the turtle module's end_fill function.
1337
Brett Cannon53ab5b72006-06-22 16:49:14 +00001338- Bug #1510580: The 'warnings' module improperly required that a Warning
1339 category be either a types.ClassType and a subclass of Warning. The proper
1340 check is just that it is a subclass with Warning as the documentation states.
1341
Georg Brandlad29e632006-06-21 17:45:17 +00001342- The compiler module now correctly compiles the new try-except-finally
1343 statement (bug #1509132).
1344
Neal Norwitz60373cd2006-06-22 06:30:50 +00001345- The wsgiref package is now installed properly on Unix.
1346
Vinay Sajip28e57612006-07-01 10:45:20 +00001347- A bug was fixed in logging.config.fileConfig() which caused a crash on
1348 shutdown when fileConfig() was called multiple times.
1349
Gerhard Häring762fbd32006-07-02 17:48:30 +00001350- The sqlite3 module did cut off data from the SQLite database at the first
1351 null character before sending it to a custom converter. This has been fixed
1352 now.
1353
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001354Extension Modules
1355-----------------
1356
Tim Peters112aad32006-07-19 00:03:19 +00001357- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1358 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1359 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001360
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001361- Assigning None to pointer type fields in ctypes structures possible
1362 overwrote the wrong fields, this is fixed now.
1363
1364- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1365 on non-Windows platforms.
1366
1367- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1368 integer or long, without range checking.
1369
1370- Patch #1517790: It is now possible to use custom objects in the ctypes
1371 foreign function argtypes sequence as long as they provide a from_param
1372 method, no longer is it required that the object is a ctypes type.
1373
1374- The '_ctypes' extension module now works when Python is configured
1375 with the --without-threads option.
1376
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001377- Bug #1513646: os.access on Windows now correctly determines write
1378 access, again.
1379
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001380- Bug #1512695: cPickle.loads could crash if it was interrupted with
1381 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001383- Bug #1296433: parsing XML with a non-default encoding and
1384 a CharacterDataHandler could crash the interpreter in pyexpat.
1385
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001386- Patch #1516912: improve Modules support for OpenVMS.

1392
Tim Peters32a83612006-07-10 21:08:24 +00001393- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001394 Previously, the slight difference could cause compilation errors of the
1395 'zlib' module on systems with more than one version of zlib.
1396
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001397- The MSI compileall step was fixed to also support a TARGETDIR
1398 with spaces in it.

Nick Coghlan2d792252006-07-06 13:47:18 +00001415- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1416 documentation for the warnings module.
1417
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001418- Patch #1509163: MS Toolkit Compiler no longer available.

1429-----------------
1430
Georg Brandla56b9152006-06-19 06:35:54 +00001431- Patch #1507676: Error messages returned by invalid abstract object operations
1432 (such as iterating over an integer) have been improved and now include the
1433 type of the offending object to help with debugging.
1434
Brett Cannonea3912b2006-06-13 21:46:41 +00001435- Bug #992017: A classic class that defined a __coerce__() method that returned
1436 its arguments swapped would infinitely recurse and segfault the interpreter.
1437
Neal Norwitz909eb122006-06-12 02:13:21 +00001438- Fix the socket tests so they can be run concurrently.
1439
Neal Norwitzb9845e72006-06-12 02:11:18 +00001440- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001441 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001442
Brett Cannon22565aa2006-06-09 22:31:23 +00001443- Bug #532646: object.__call__() will continue looking for the __call__
1444 attribute on objects until one without one is found. This leads to recursion
1445 when you take a class and set its __call__ attribute to an instance of the
1446 class. Originally fixed for classic classes, but this fix is for new-style.
1447 Removes the infinite_rec_3 crasher.
1448
Georg Brandl24250812006-06-09 18:45:48 +00001449- The string and unicode methods startswith() and endswith() now accept
1450 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1451
Brett Cannonde3b0522006-06-08 17:00:45 +00001452- Buffer objects, at the C level, never used the char buffer
1453 implementation even when the char buffer for the wrapped object was
1454 explicitly requested (originally returned the read or write buffer).
1455 Now a TypeError is raised if the char buffer is not present but is
1456 requested.
1457
Georg Brandlddbaa662006-06-04 21:56:52 +00001458- Patch #1346214: Statements like "if 0: suite" are now again optimized
1459 away like they were in Python 2.4.
1460
Georg Brandlb7c8f542006-05-27 12:30:25 +00001461- Builtin exceptions are now full-blown new-style classes instead of
1462 instances pretending to be classes, which speeds up exception handling
1463 by about 80% in comparison to 2.5a2.
1464
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001465- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1466 Unicode 4.1.
1467
Georg Brandlf4ef1162006-05-26 18:03:31 +00001468- Patch #921466: sys.path_importer_cache is now used to cache valid and
1469 invalid file paths for the built-in import machinery which leads to
1470 fewer open calls on startup.
1471
Tim Peters696cf432006-05-24 21:10:40 +00001472- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1473 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1474 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1475 the number of input digits (it was and remains linear-time for bases
1476 2, 4, 8, 16 and 32).
1477
Tim Petersb713ec22006-05-23 18:45:30 +00001478- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1479 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1480 an integer close to ``sys.maxint``. This was repaired by patch
1481 #1335972, which also gives a nice speedup.
1482
Richard Jonescebbefc2006-05-23 18:28:17 +00001483- Patch #1337051: reduced size of frame objects.
1484
1485- PyErr_NewException now accepts a tuple of base classes as its
1486 "base" parameter.
1487
Richard Jones7c88dcc2006-05-23 10:37:38 +00001488- Patch #876206: function call speedup by retaining allocated frame
1489 objects.
1490
Georg Brandl7b90e162006-05-18 07:01:27 +00001491- Bug #1462152: file() now checks more thoroughly for invalid mode
1492 strings and removes a possible "U" before passing the mode to the
1493 C library function.
1494
Neal Norwitz1004a532006-05-15 07:17:23 +00001495- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1496
Neal Norwitz373f0a72006-05-15 07:04:36 +00001497- Bug #1487966: Fix SystemError with conditional expression in assignment
1498
Martin v. Löwis879768d2006-05-11 13:28:43 +00001499- WindowsError now has two error code attributes: errno, which carries
1500 the error values from errno.h, and winerror, which carries the error
1501 values from winerror.h. Previous versions put the winerror.h values
1502 (from GetLastError()) into the errno attribute.
1503
Martin v. Löwis77736712006-05-04 05:51:03 +00001504- Patch #1475845: Raise IndentationError for unexpected indent.
1505
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001506- Patch #1479181: split open() and file() from being aliases for each other.
1507
Tim Peters44bd9862006-06-01 13:49:23 +00001508- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1509 methods were always silently ignored by dictionaries when comparing keys.
1510 They are now passed through (except when using the C API function
1511 ``PyDict_GetItem()``, whose semantics did not change).
1512
1513- Bug #1456209: In some obscure cases it was possible for a class with a
1514 custom ``__eq__()`` method to confuse dict internals when class instances
1515 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1516 No, you don't have any code that did this ;-)

1519-----------------
1520
Trent Mick960a3f82006-06-28 20:30:41 +00001521- Bug #1295808: expat symbols should be namespaced in pyexpat
1522
1523- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1524
Brett Cannon6ee7d012006-06-08 16:23:04 +00001525- Change binascii.hexlify to accept a read-only buffer instead of only a char
1526 buffer and actually follow its documentation.
1527
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001528- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1529
Nick Coghlanc649ec52006-05-29 12:43:05 +00001530- Patch #1478788 (modified version): The functional extension module has
1531 been renamed to _functools and a functools Python wrapper module added.
1532 This provides a home for additional function related utilities that are
1533 not specifically about functional programming. See PEP 309.
1534
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001535- Patch #1493701: performance enhancements for struct module.
1536
Georg Brandl378d5922006-05-17 14:26:50 +00001537- Patch #1490224: time.altzone is now set correctly on Cygwin.
1538
Georg Brandl8d3342b2006-05-16 07:38:27 +00001539- Patch #1435422: zlib's compress and decompress objects now have a
1540 copy() method.
1541
Andrew MacIntyre92913322006-06-13 15:04:24 +00001542- Patch #1454481: thread stack size is now tunable at runtime for thread
1543 enabled builds on Windows and systems with Posix threads support.
1544
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001545- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1546 (up to the system limit of 32K characters).
1547
1548- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1549 As a result, these functions now raise WindowsError instead of OSError.
1550
Tim Peters7a822da2006-05-25 21:50:17 +00001551- ``time.clock()`` on Win64 should use the high-performance Windows
1552 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1553 Windows platforms).
1554
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001555- Calling Tk_Init twice is refused if the first call failed as that
1556 may deadlock.
1557
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001558- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1559 accept it without potentially using an uninitialized pointer.
1560
1561- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1562 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1563 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001564
Gregory P. Smith372b5832006-06-05 18:48:21 +00001565- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001566 [pybsddb project SF patch number 1466734]
1567
Gregory P. Smith372b5832006-06-05 18:48:21 +00001568- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1569 parameter is supplied. [SF pybsddb bug #1477863]
1570
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001571- bsddb: the __len__ method of a DB object has been fixed to return correct
1572 results. It could previously incorrectly return 0 in some cases.
1573 Fixes SF bug 1493322 (pybsddb bug 1184012).
1574
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001575- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1576 aborts the db transaction safely when a modifier callback fails.
1577 Fixes SF python patch/bug #1408584.
1578
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001579- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001580 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001581 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1582 database calls that would previously deadlock. [SF python bug #775414]
1583
Vinay Sajip28e57612006-07-01 10:45:20 +00001584- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1603 classes.
1604
Georg Brandl83cc0d02006-06-14 08:50:03 +00001605- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1606 mime.types file for determining MIME types.
1607
Georg Brandl2605ca82006-06-14 06:08:31 +00001608- Bug #1339007: Shelf objects now don't raise an exception in their
1609 __del__ method when initialization failed.
1610
Martin v. Löwisd8251432006-06-14 05:21:04 +00001611- Patch #1455898: The MBCS codec now supports the incremental mode for
1612 double-byte encodings.
1613
Tim Peters43898b42006-06-14 04:09:25 +00001614- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1615 guarantee that adjacent triples in the return list always describe
1616 non-adjacent blocks. Previously, a pair of matching blocks could end
1617 up being described by multiple adjacent triples that formed a partition
1618 of the matching pair.
1619
Greg Ward0e0c9f42006-06-11 16:24:11 +00001620- Bug #1498146: fix optparse to handle Unicode strings in option help,
1621 description, and epilog.
1622
Greg Wardd1c797e2006-06-11 14:42:41 +00001623- Bug #1366250: minor optparse documentation error.
1624
Greg Ward7f547402006-06-11 00:40:49 +00001625- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1626 clarify docs.
1627
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001628- The wsgiref package has been added to the standard library.
1629
Nick Coghlan676725d2006-06-08 13:54:49 +00001630- The functions update_wrapper() and wraps() have been added to the functools
1631 module. These make it easier to copy relevant metadata from the original
1632 function when writing wrapper functions.
1633
Tim Petersd6a9eef2006-06-05 01:48:21 +00001634- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1635 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001636
Martin v. Löwis3f767792006-06-04 19:36:28 +00001637- Patch #1359618: Speed up charmap encoder by using a trie structure
1638 for lookup.
1639
Tim Petersd609b1a2006-06-02 23:22:51 +00001640- The functions in the ``pprint`` module now sort dictionaries by key
1641 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1642 if and only if its display required more than one line, although that
1643 wasn't documented. The new behavior increases predictability; e.g.,
1644 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1645
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001646- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1647 (thanks for J. J. Lee).
1648
Georg Brandl2b330372006-05-28 20:23:12 +00001649- Patch #1496206: improve urllib2 handling of passwords with respect to
1650 default HTTP and HTTPS ports.
1651
George Yoshidaf3c65de2006-05-28 16:39:09 +00001652- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1653
Bob Ippolito7298f272006-05-23 18:43:47 +00001654- Patch #1281707: speed up gzip.readline.
1655
Georg Brandlb89316f2006-05-17 15:51:16 +00001656- Patch #1180296: Two new functions were added to the locale module:
1657 format_string() to get the effect of "format % items" but locale-aware,
1658 and currency() to format a monetary number with currency sign.
1659
Georg Brandle3a25832006-05-17 14:56:04 +00001660- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1661 and several features added, such as speed and geometry control.
1662
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001663- Patch #1488881: add support for external file objects in bz2 compressed
1664 tarfiles.
1665
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001666- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1667 stdout arguments, making it possible to redirect input and output
1668 for remote debugging.
1669
1670- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1671 a couple of issues, notably handling of long file names using the
1672 GNU LONGNAME extension.
1673
1674- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1675 new flag when ``name`` is already the name of an option flag.
1676
1677- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1678 package.
1679
1680- Patch #1472854: make the rlcompleter.Completer class usable on non-
1681 UNIX platforms.
1682
1683- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1684
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001685- Bug #1472827: correctly escape newlines and tabs in attribute values in
1686 the saxutils.XMLGenerator class.

1721Core and builtins
1722-----------------
1723
Thomas Heller1b046642006-04-18 18:51:06 +00001724- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1725 by converting these apis from macros into exported functions again:
1726
1727 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1728 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1729 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1730 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1731 PyRun_String Py_CompileString
1732
Martin v. Löwis45294a92006-04-18 06:24:08 +00001733- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1734
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001735- All uses of PyStructSequence_InitType have been changed to initialize
1736 the type objects only once, even if the interpreter is initialized
1737 multiple times.
1738
Neal Norwitz61546162006-04-14 05:20:28 +00001739- Bug #1454485, array.array('u') could crash the interpreter. This was
1740 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1741 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1742
1743- Py_UNICODE is unsigned. It was always documented as unsigned, but
1744 due to a bug had a signed value in previous versions.
1745
Tim Peters3a5e8b12006-04-11 01:44:07 +00001746- Patch #837242: ``id()`` of any Python object always gives a positive
1747 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1748 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001749 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001750 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001751
Tim Peters3a5e8b12006-04-11 01:44:07 +00001752 def __hash__(self):
1753 return id(self) # WRONG
1754
1755 because a hash result must be a (short) Python int but it was always
1756 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001757 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001758 was always usable as a hash value before this patch. That's no longer
1759 necessarily so.
1760
1761- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001762 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001763 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001764 #1454844)
1765
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001766- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1767 involving generators that have paused outside of any ``try`` or ``with``
1768 blocks. (In 2.5a1, a paused generator that was part of a reference
1769 cycle could not be garbage collected, regardless of whether it was
1770 paused in a ``try`` or ``with`` block.)

1784 the cachesize parameter.
1785
1786- Bug #1149413: bsddb.*open() no longer raises an exception when using
1787 a temporary db (file=None) with the 'n' flag to truncate on open.
1788
1789- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1790 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001791
Armin Rigoa9017c32006-04-19 11:50:27 +00001792- Patch #1062014: AF_UNIX sockets under Linux have a special
1793 abstract namespace that is now fully supported.

1796-------
1797
Peter Astrand7d1d4362006-07-14 14:04:45 +00001798- Bug #1223937: subprocess.CalledProcessError reports the exit status
1799 of the process using the returncode attribute, instead of
1800 abusing errno.
1801
Tim Peters711bf302006-04-25 03:31:36 +00001802- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1803 a doctest to be skipped (the code is not run, and the expected output
1804 or exception is ignored).
1805
Nick Coghlanda2268f2006-04-24 04:37:15 +00001806- Fixed contextlib.nested to cope with exceptions being raised and
1807 caught inside exit handlers.
1808
Greg Wardab05edc2006-04-23 03:47:58 +00001809- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1810 hex, octal, or binary; add ``append_const`` action; keep going if
1811 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1812 added ``epilog`` for better help generation).
1813
Tim Peters21fbd572006-04-21 21:18:10 +00001814- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1815 called from a thread spawned as a side effect of importing a module.
1816
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001817- The pydoc module now supports documenting packages contained in
1818 .zip or .egg files.
1819
1820- The pkgutil module now has several new utility functions, such
1821 as ``walk_packages()`` to support working with packages that are either
1822 in the filesystem or zip files.
1823
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001824- The mailbox module can now modify and delete messages from
1825 mailboxes, in addition to simply reading them. Thanks to Gregory
1826 K. Johnson for writing the code, and to the 2005 Google Summer of
1827 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001828

1839 Windows. Bug #1469163.
1840
Phillip J. Eby47032112006-04-11 01:07:43 +00001841- The warnings, linecache, inspect, traceback, site, and doctest modules
1842 were updated to work correctly with modules imported from zipfiles or
1843 via other PEP 302 __loader__ objects.

Skip Montanaro262fb922006-04-21 02:31:07 +00001852- The pstats.Stats class accepts an optional stream keyword argument to
1853 direct output to an alternate file-like object.
1854
Anthony Baxter51bcb682006-04-05 14:51:42 +00001855Build
1856-----
1857
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001858- The Makefile now has a reindent target, which runs reindent.py on
1859 the library.
1860
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001861- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001864
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001865- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1866 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001867 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001868 CXX from --with-cxx-main, see description in README.
1869
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001870- Patch #1429775: Link extension modules with the shared libpython.
1871

1873
Tim Peters8931ff12006-05-13 23:28:20 +00001874- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1875 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1876 and "%zu" for unsigned integers of type ``size_t``.
1877
Anthony Baxter51bcb682006-04-05 14:51:42 +00001878Tests
1879-----
1880
Nick Coghlanda2268f2006-04-24 04:37:15 +00001881- test_contextlib now checks contextlib.nested can cope with exceptions
1882 being raised and caught inside exit handlers.
1883
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001884- test_cmd_line now checks operation of the -m and -c command switches
1885
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001886- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1887 it separately and by hand. It also wasn't cleaning up its changes to
1888 the current Decimal context.
1889
Thomas Woutersabd08882006-04-26 15:53:30 +00001890- regrtest.py now has a -M option to run tests that test the new limits of
1891 containers, on 64-bit architectures. Running these tests is only sensible
1892 on 64-bit machines with more than two gigabytes of memory. The argument
1893 passed is the maximum amount of memory for the tests to use.
1894
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001895Tools

1902-------------
1903
Tim Petersb06d28c2006-05-12 01:57:59 +00001904- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1905
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001906- PEP 343: Added Context Types section to the library reference
1907 and attempted to bring other PEP 343 related documentation into
1908 line with the implementation and/or python-dev discussions.
1909
Tim Peters8dc73d22006-04-24 02:03:16 +00001910- Bug #1337990: clarified that ``doctest`` does not support examples
1911 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001914What's New in Python 2.5 alpha 1?
1915=================================
1916
Anthony Baxterebed3f62006-04-03 15:03:44 +00001917*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001918
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001919Core and builtins
1920-----------------
1921
Nick Coghlan43832302006-04-23 17:04:07 +00001922- PEP 338: -m command line switch now delegates to runpy.run_module
1923 allowing it to support modules in packages and zipfiles
1924
Martin v. Löwisc661b882006-04-20 04:54:23 +00001925- On Windows, .DLL is not an accepted file name extension for
1926 extension modules anymore; extensions are only found if they
1927 end in .PYD.
1928
Martin v. Löwisea62d252006-04-03 10:56:49 +00001929- Bug #1421664: sys.stderr.encoding is now set to the same value as
1930 sys.stdout.encoding.
1931
Neal Norwitz92e212f2006-04-03 04:48:37 +00001932- __import__ accepts keyword arguments.
1933
Georg Brandlccadf842006-03-31 18:54:53 +00001934- Patch #1460496: round() now accepts keyword arguments.
1935
Anthony Baxter262c00a2006-03-30 10:53:17 +00001936- Fixed bug #1459029 - unicode reprs were double-escaped.
1937
Hye-Shik Changd478f342006-03-23 12:32:36 +00001938- Patch #1396919: The system scope threads are reenabled on FreeBSD
1939 5.4 and later versions.
1940
Neal Norwitze98ccf62006-03-23 05:39:47 +00001941- Bug #1115379: Compiling a Unicode string with an encoding declaration
1942 now gives a SyntaxError.
1943
Georg Brandlabd1ff82006-03-18 07:59:59 +00001944- Previously, Python code had no easy way to access the contents of a
1945 cell object. Now, a ``cell_contents`` attribute has been added
1946 (closes patch #1170323).
1947
Tim Peterscf79aac2006-03-16 01:14:46 +00001948- Patch #1123430: Python's small-object allocator now returns an arena to
1949 the system ``free()`` when all memory within an arena becomes unused
1950 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1951 freed. Some applications will see a drop in virtual memory size now,
1952 especially long-running applications that, from time to time, temporarily
1953 use a large number of small objects. Note that when Python returns an
1954 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001955 platform C library will in turn return that memory to the operating system.
1956 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001957 appears to be effective at least on Microsoft C and gcc-based systems.
1958 Thanks to Evan Jones for hard work and patience.
1959
Georg Brandl533ff6f2006-03-08 18:09:27 +00001960- Patch #1434038: property() now uses the getter's docstring if there is
1961 no "doc" argument given. This makes it possible to legitimately use
1962 property() as a decorator to produce a read-only property.
1963
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001964- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1965 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1966 of requiring an int or long in slicing and a few other contexts, enabling
1967 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1968
Neal Norwitz995acdf2006-03-07 05:01:00 +00001969- Fixed various bugs reported by Coverity's Prevent tool.
1970
Brett Cannonbf364092006-03-01 04:25:17 +00001971- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1972 new exception base class, BaseException, which has a new message attribute.
1973 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1974 Raising a string exception now raises a DeprecationWarning.
1975
Thomas Woutersfb609f42006-02-28 16:37:25 +00001976- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1977 explicitly relative, using 'from .module import name' to mean 'from the same
1978 package as this module is in. Imports without dots still default to the
1979 old relative-then-absolute, unless 'from __future__ import
1980 absolute_import' is used.
1981
Brett Cannona7446e32006-02-27 23:39:10 +00001982- Properly check if 'warnings' raises an exception (usually when a filter set
1983 to "error" is triggered) when raising a warning for raising string
1984 exceptions.
1985
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001986- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001987 The name was removed from Include/code.h.
1988
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001989- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001990
Guido van Rossum1968ad32006-02-25 22:38:04 +00001991- Patch 1433928:
1992 - The copy module now "copies" function objects (as atomic objects).
1993 - dict.__getitem__ now looks for a __missing__ hook before raising
1994 KeyError.
1995
Tim Peters84ef21c2006-02-28 20:39:06 +00001996- PEP 343: with statement implemented. Needs ``from __future__ import
1997 with_statement``. Use of 'with' as a variable will generate a warning.
1998 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001999 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002000 The following objects have __context__ methods:
2001 - The built-in file type.
2002 - The thread.LockType type.
2003 - The following types defined by the threading module:
2004 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2005 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002006
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002007- Fix the encodings package codec search function to only search
2008 inside its own package. Fixes problem reported in patch #1433198.
2009
2010 Note: Codec packages should implement and register their own
2011 codec search function. PEP 100 has the details.
2012
Tim Peters9ea89d22006-06-04 03:26:02 +00002013- PEP 353: Using ``Py_ssize_t`` as the index type.
2014
2015- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2016 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2017 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2018 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2019 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002020
Neal Norwitzfc76d632006-01-10 06:03:13 +00002021- Patch #1400181, fix unicode string formatting to not use the locale.
2022 This is how string objects work. u'%f' could use , instead of .
2023 for the decimal point. Now both strings and unicode always use periods.
2024
Neal Norwitz671b9e32006-01-09 07:07:12 +00002025- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2026 configure would break checking curses.h.
2027
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002028- Bug #959576: The pwd module is now builtin. This allows Python to be
2029 built on UNIX platforms without $HOME set.
2030
Neal Norwitzc10978f2005-12-19 06:07:16 +00002031- Bug #1072182, fix some potential problems if characters are signed.
2032
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002033- Bug #889500, fix line number on SyntaxWarning for global declarations.
2034
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002035- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2036
Neal Norwitze7214a12005-12-18 05:03:17 +00002037- Support for converting hex strings to floats no longer works.
2038 This was not portable. float('0x3') now raises a ValueError.
2039
Barry Warsaw2a38a862005-12-18 01:27:35 +00002040- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002041 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002042 is now displayed in interactive prompt banner.
2043
Georg Brandlfa166682005-12-17 21:45:17 +00002044- Implementation of PEP 341 - Unification of try/except and try/finally.
2045 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002046 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002047
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002048- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2049 now encodes backslash correctly.
2050
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002051- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2052
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002053- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002054 and long longs.
2055
Neal Norwitz67715f02005-11-09 06:59:35 +00002056- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002057 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002058 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002059
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002060- Replaced most Unicode charmap codecs with new ones using the
2061 new Unicode translate string feature in the builtin charmap
2062 codec; the codecs were created from the mapping tables available
2063 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2064 encodings now include a mapping for the Apple logo)
2065
Tim Peterse3547fd2005-12-16 23:13:57 +00002066- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002067
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002068- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002069
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002070- A new AST parser implementation was completed. The abstract
2071 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002072 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002073
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002074- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002075 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2076
Neal Norwitz708e51a2005-10-03 04:48:15 +00002077- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2078
Neal Norwitz11bd1192005-10-03 00:54:56 +00002079- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2080 Provide a warning when a directory is passed on the command line.
2081
Neal Norwitz40d37812005-10-02 01:48:49 +00002082- Fix segfault with invalid coding.
2083
2084- SF bug #772896: unknown encoding results in MemoryError.
2085
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002086- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002087 supported a __len__() method which evaluated to False when the iterator
2088 was empty.
2089
Guido van Rossum630db602005-09-20 18:49:54 +00002090- On 64-bit platforms, when __len__() returns a value that cannot be
2091 represented as a C int, raise OverflowError.
2092
Skip Montanarof8948ca2005-09-19 03:54:46 +00002093- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002094 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002095
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002096- SF bug #893549: parsing keyword arguments was broken with a few format
2097 codes.
2098
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002099- Changes donated by Elemental Security to make it work on AIX 5.3
2100 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2101 bug #105470: test_pwd fails on 64bit system (Opteron).
2102
Guido van Rossum539c6622005-09-14 17:49:54 +00002103- Changes donated by Elemental Security to make it work on HP-UX 11 on
2104 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2105
Georg Brandl4550b8d2005-08-26 06:43:52 +00002106- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002107 (fixes bug #1119418).
2108
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002109- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2110
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002111- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2112 exceptions that cause a function to exit.
2113
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002114- The implementation of set() and frozenset() was revised to use its
2115 own internal data structure. Memory consumption is reduced by 1/3
2116 and there are modest speed-ups as well. The API is unchanged.
2117
Tim Petersde7990b2005-07-17 23:45:23 +00002118- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2119
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002120- SF bug #1229429: PyObject_CallMethod failed to decrement some
2121 reference counts in some error exit cases.
2122
Tim Petersecc6e6a2005-07-10 22:30:55 +00002123- SF bug #1185883: Python's small-object memory allocator took over
2124 a block managed by the platform C library whenever a realloc specified
2125 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002126 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002127 portable way to copy data from the C-managed block into Python's
2128 small-object space without risking a memory fault. Python's small-object
2129 realloc now leaves such blocks under the control of the platform C
2130 realloc.
2131
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002132- SF bug #1232517: An overflow error was not detected properly when
2133 attempting to convert a large float to an int in os.utime().
2134
Raymond Hettinger3296e692005-06-29 23:29:56 +00002135- SF bug #1224347: hex longs now print with lowercase letters just
2136 like their int counterparts.
2137
Michael W. Hudson188d4362005-06-20 16:52:57 +00002138- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2139 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2140 interpreter states; back out that fix and do a better job (see
2141 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2142 for a longer write-up of the problem).
2143
Michael W. Hudsondf888462005-06-03 14:41:55 +00002144- SF patch #1180995: marshal now uses a binary format by default when
2145 serializing floats.
2146
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002147- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2148 the routines that promise to produce IEEE 754 binary representations
2149 of floats now simply copy bytes around.
2150
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002151- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2152 278.
2153
Brett Cannonc3647ac2005-04-26 03:45:26 +00002154- patch #1109424: int, long, float, complex, and unicode now check for the
2155 proper magic slot for type conversions when subclassed. Previously the
2156 magic slot was ignored during conversion. Semantics now match the way
2157 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002158 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002159 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002160 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002161
Barry Warsawc8d907c2005-04-19 23:43:40 +00002162- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2163 NULL, now raise an AttributeError when attempting to set or delete the
2164 attribute. Previously a TypeError was raised, but this was inconsistent
2165 with the equivalent pure-Python implementation.
2166
Michael W. Hudson774479c2005-04-18 08:46:17 +00002167- It is now safe to call PyGILState_Release() before
2168 PyEval_InitThreads() (note that if there is reason to believe there
2169 are multiple threads around you still must call PyEval_InitThreads()
2170 before using the Python API; this fix is for extension modules that
2171 have no way of knowing if Python is multi-threaded yet).
2172
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002173- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2174 disabled caused a crash.
2175
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002176- Bug #1165306: instancemethod_new allowed the creation of a method
2177 with im_class == im_self == NULL, which caused a crash when called.
2178
Tim Petersecc6e6a2005-07-10 22:30:55 +00002179- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002180 fixes the crash seen in bug #1165761
2181
Raymond Hettinger96229b12005-03-11 06:49:40 +00002182- Added two new builtins, any() and all().
2183
Brett Cannon409d8f22005-03-05 06:47:57 +00002184- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002185 (e.g., ``class C(): pass`` is no longer a syntax error).
2186 Patch #1176012 added support to the 'parser' module and 'compiler' package
2187 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002188
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002189- Patch #1115086: Support PY_LONGLONG in structmember.
2190
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002191- Bug #1155938: new style classes did not check that __init__() was
2192 returning None.
2193
Tim Petersecc6e6a2005-07-10 22:30:55 +00002194- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002195 ('\') with a specific error message.
2196
Martin v. Löwisff232d72005-03-03 09:24:38 +00002197- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2198
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002199- Bug #1124295: the __name__ attribute of file objects was
2200 inadvertently made inaccessible in restricted mode.
2201
Tim Petersecc6e6a2005-07-10 22:30:55 +00002202- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002203 an ferror() call.
2204
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002205- min() and max() now support key= arguments with the same meaning as in
2206 list.sort().
2207
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002208- The peephole optimizer now performs simple constant folding in expressions:
2209 (2+3) --> (5).
2210
Raymond Hettingera422c342005-01-11 03:03:27 +00002211- set and frozenset objects can now be marshalled. SF #1098985.
2212
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002213- Bug #1077106: Poor argument checking could cause memory corruption
2214 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002215
Jeremy Hyltonab630502005-02-04 18:44:06 +00002216- The parser did not complain about future statements in illegal
2217 positions. It once again reports a syntax error if a future
2218 statement occurs after anything other than a doc string.
2219
Neil Schemenauercf52c072005-08-12 17:34:58 +00002220- Change the %s format specifier for str objects so that it returns a
2221 unicode instance if the argument is not an instance of basestring and
2222 calling __str__ on the argument returns a unicode instance.
2223
Tim Petersf4e69282006-02-27 17:15:31 +00002224- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2225 current thread state when the auto-GIL-state machinery knows about
2226 it (since the thread state is being deleted, continuing to remember it
2227 can't help, but can hurt if another thread happens to get created with
2228 the same thread id).
2229
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002230Extension Modules
2231-----------------
2232

Neal Norwitz10be10c2006-03-16 06:50:13 +00002246 util, whatsound, whrandom, zmod
2247
2248- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2249
2250- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002251 is deprecated. The undocumented re.engine variable no longer exists.
2252
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002253- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2254 SS2 (single-shift 2) escape sequences correctly.
2255
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002256- The unicodedata module was updated to the 4.1 version of the Unicode
2257 database. The 3.2 version is still available as unicodedata.db_3_2_0
2258 for applications that require this specific version (such as IDNA).
2259
Neal Norwitzb62c4332006-03-04 18:35:47 +00002260- The timing module is no longer built by default. It was deprecated
2261 in PEP 4 in Python 2.0 or earlier.
2262
Guido van Rossum1968ad32006-02-25 22:38:04 +00002263- Patch 1433928: Added a new type, defaultdict, to the collections module.
2264 This uses the new __missing__ hook behavior added to dict (see above).
2265
Georg Brandldbd83392006-02-20 09:42:33 +00002266- Bug #854823: socketmodule now builds on Sun platforms even when
2267 INET_ADDRSTRLEN is not defined.
2268
Georg Brandlf4f44152006-02-18 22:29:33 +00002269- Patch #1393157: os.startfile() now has an optional argument to specify
2270 a "command verb" to invoke on the file.
2271
Neal Norwitz082b2df2006-02-07 07:04:46 +00002272- Bug #876637, prevent stack corruption when socket descriptor
2273 is larger than FD_SETSIZE.
2274
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002275- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2276 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2277 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

Martin v. Löwis57a34e82006-02-04 19:12:37 +00002279- Patch #1422385: The nis module now supports access to domains other
2280 than the system default domain.
2281
Martin v. Löwis14694662006-02-03 12:54:16 +00002282- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2283 are reported, the limit on path name lengths is removed, and stat reports
2284 WindowsError now (instead of OSError).
2285
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002286- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2361 the request code argument, which results in more C-like behaviour
2362 for large or negative values.
2363
Tim Petersecc6e6a2005-07-10 22:30:55 +00002364- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2379
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002380- operator.itemgetter() and operator.attrgetter() now support retrieving

2406
Raymond Hettingerb2594052004-12-05 09:25:51 +00002407- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002420- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2421 been renamed to have only a single underscore prefix. This was done to
2422 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002423
Nick Coghlan43832302006-04-23 17:04:07 +00002424- PEP 338: new module runpy defines a run_module function to support
2425 executing modules which provide access to source code or a code object
2426 via the PEP 302 import mechanisms.
2427
Anthony Baxter93f5b932006-04-03 08:05:07 +00002428- The email module's parsedate_tz function now sets the daylight savings

2436 in attribute values.
2437
Anthony Baxterc51ee692006-04-01 00:57:31 +00002438- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002439 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002440 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002441 module will not be built.
2442
Tim Petersc17976e2006-04-01 00:26:53 +00002443- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2444 aren't officially supported here, and trying to use them will probably
2445 raise an exception some day. But dicts have been allowed, and "mostly
2446 worked", so support for them won't go away without warning.
2447
Georg Brandl338ef7d2006-03-31 18:42:16 +00002448- Bug #1445068: getpass.getpass() can now be given an explicit stream
2449 argument to specify where to write the prompt.
2450
Georg Brandl22ec80b2006-03-31 18:25:44 +00002451- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2458
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002459- Queue.Queue objects now support .task_done() and .join() methods
2460 to make it easier to monitor when daemon threads have completed
2461 processing all enqueued tasks. Patch #1455676.
2462
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002463- popen2.Popen objects now preserve the command in a .cmd attribute.

2466
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002467- email 4.0 package now integrated. This is largely the same as the email 3.0
2468 package that was included in Python 2.3, except that PEP 8 module names are
2469 now used (e.g. mail.message instead of email.Message). The MIME classes
2470 have been moved to a subpackage (e.g. email.mime.text instead of
2471 email.MIMEText). The old names are still supported for now. Several
2472 deprecated Message methods have been removed and lots of bugs have been
2473 fixed. More details can be found in the email package documentation.
2474
Walter Dörwald40108c92006-03-27 08:15:44 +00002475- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2476 (a subclass of tuple) that provides incremental decoders and encoders
2477 (a way to use stateful codecs without the stream API). Python functions
2478 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2479 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2480 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002481
Walter Dörwald067db482006-03-15 22:17:27 +00002482- Patch #1359365: Calling next() on a closed StringIO.String object raises
2483 a ValueError instead of a StopIteration now (like file and cString.String do).
2484 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2485 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002486
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002487- A regrtest option -w was added to re-run failed tests in verbose mode.

2491
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002492- The function get_count() has been added to the gc module, and gc.collect()
2493 grew an optional 'generation' argument.
2494
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002495- A library msilib to generate Windows Installer files, and a distutils

2497
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002498- PEP 343: new module contextlib.py defines decorator @contextmanager
2499 and helpful context managers nested() and closing().
2500
Martin v. Löwis415ed932006-02-27 19:56:30 +00002501- The compiler package now supports future imports after the module docstring.
2502

2504 not allowed by the specs.
2505
Georg Brandlc98eeed2006-02-19 14:57:47 +00002506- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002535 specifications, raises IOErrors when proxies for unsupported protocols
2536 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002559 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2560 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2561 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2562 Ronald L. Rivest offered this advice for Python:
2563
2564 "The consensus of researchers in this area (at least as
2565 expressed at the NIST Hash Function Workshop 10/31/05),
2566 is that SHA-256 is a good choice for the time being, but
2567 that research should continue, and other alternatives may
2568 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002569
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002570- Added a subset of Fredrik Lundh's ElementTree package. Available

2623 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002624 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002625

2648
Georg Brandl9e43acf2005-07-04 17:16:07 +00002649- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2650 as this can cause problems with apps closing all file descriptors.

2663 Bug #1224621.
2664
Raymond Hettinger68c04532005-06-10 11:05:19 +00002665- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002666 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002667 the generate_tokens() function now accepts a callable argument that
2668 terminates by raising StopIteration.
2669
Georg Brandl9166e1a2005-06-04 09:20:03 +00002670- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2671
Georg Brandl268e61c2005-06-03 14:28:50 +00002672- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

2674
Skip Montanaro174dd222005-05-14 20:54:16 +00002675- Patch #1120353: The xmlrpclib module provides better, more transparent,

2678 class at all.
2679
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002680- distutils.commands.upload was added to support uploading distribution
2681 files to PyPI.
2682
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002683- distutils.commands.register now encodes the data as UTF-8 before posting
2684 them to PyPI.
2685
Raymond Hettinger267b8682005-03-27 10:47:39 +00002686- decimal operator and comparison methods now return NotImplemented
2687 instead of raising a TypeError when interacting with other types. This
2688 allows other classes to implement __radd__ style methods and have them
2689 work as expected.
2690
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002691- Bug #1163325: Decimal infinities failed to hash. Attempting to
2692 hash a NaN raised an InvalidOperation instead of a TypeError.
2693
Tim Petersecc6e6a2005-07-10 22:30:55 +00002694- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002695 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2696

2728
Guido van Rossumd0641422005-02-03 15:01:24 +00002729- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2730 disables recursive traversal through instance attributes, which can
2731 be exploited in various ways.
2732
Tim Peterse3547fd2005-12-16 23:13:57 +00002733- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002734 flags on the HTTP listening socket.
2735
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002736- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2737 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2738
Fred Drakefbdeaad2006-07-29 16:56:15 +00002739- Patches #893642, #1039083: add allow_none, encoding arguments to
2740 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002741
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002742- Bug #1110478: Revert os.environ.update to do putenv again.
2743
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002744- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2745
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002746- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2747
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002748- Enhancements to the csv module:
2749
2750 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002751 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002752 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002753 + Dialect parameter parsing has been re-implemented to improve error
2754 reporting.
2755 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2756 dictates.
2757 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002758 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002759 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002760 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2761 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002762 + reader now allows \r characters to be quoted (previously it only allowed
2763 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002764 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002765 + Dialect classes passed to the module are no longer instantiated by
2766 the module before being parsed (the former validation scheme required
2767 this, but the mechanism was unreliable).
2768 + The dialect registry now contains instances of the internal
2769 C-coded dialect type, rather than references to python objects.
2770 + the internal c-coded dialect type is now immutable.
2771 + register_dialect now accepts the same keyword dialect specifications
2772 as the reader and writer, allowing the user to register dialects
2773 without first creating a dialect class.
2774 + a configurable limit to the size of parsed fields has been added -
2775 previously, an unmatched quote character could result in the entire
2776 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002777 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002778 the parser field size limit (returning the former limit). The initial
2779 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002780 + A line_num attribute has been added to the reader object, which tracks
2781 the number of lines read from the source iterator. This is not
2782 the same as the number of records returned, as records can span
2783 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002784 + reader and writer objects were not being registered with the cyclic-GC.
2785 This has been fixed.
2786
Brett Cannone6539c42005-01-08 02:43:53 +00002787- _DummyThread objects in the threading module now delete self.__block that is
2788 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2789 lock primitives tend to be limited in number and thus should not be wasted on
2790 a _DummyThread object. Fixes bug #1089632.
2791
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002792- The imghdr module now detects Exif files.
2793
Raymond Hettinger6065d322004-12-20 23:51:53 +00002794- StringIO.truncate() now correctly adjusts the size attribute.
2795 (Bug #951915).
2796
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002797- locale.py now uses an updated locale alias table (built using
2798 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2799 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002800 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002801
Raymond Hettinger3557f422004-12-07 12:02:02 +00002802- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2803
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002804- the pickle module no longer accepts the deprecated None option in the
2805 args tuple returned by __reduce__().
2806
Brett Cannon84667c02004-12-07 03:25:18 +00002807- optparse now optionally imports gettext. This allows its use in setup.py.
2808
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002809- the pickle module no longer uses the deprecated bin parameter.
2810
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002811- the shelve module no longer uses the deprecated binary parameter.
2812
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002813- the pstats module no longer uses the deprecated ignore() method.
2814
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002815- the filecmp module no longer uses the deprecated use_statcache argument.
2816
Raymond Hettinger664347b2004-12-04 21:21:53 +00002817- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2818 extended or overridden by subclasses. Formerly, the subclassed method would
2819 be ignored by the rest of the module. (Bug #1078905).
2820
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002821- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002822 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002823
Walter Dörwald36733692004-12-22 12:50:50 +00002824- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2825 once when a size argument is given. This prevents a buffer overflow in the
2826 tokenizer with very long source lines.
2827
Barry Warsaw538561e2006-01-01 21:48:54 +00002828- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2829 immediately after creating the object, without any intervening
2830 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002831
Skip Montanaro05885812005-01-16 20:48:27 +00002832- The reconvert.quote function can now emit triple-quoted strings. The
2833 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002834
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002835- ``UserString.MutableString`` now supports negative indices in
2836 ``__setitem__`` and ``__delitem__``
2837
Greg Ward40407942005-03-05 02:53:17 +00002838- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2839 correctly.
2840
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002841- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2842 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2843 character even if the user has passed a size parameter to get a proper
2844 line ending. Remove the special handling of a "\r\n" that has been split
2845 between two lines.
2846
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002847- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2848 about illegal code points. The codec now supports PEP 293 style error
2849 handlers.
2850
Walter Dörwald78a78b02005-09-01 12:04:29 +00002851- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002852 from the input stream, so that the output is a byte string in the correct
2853 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002854
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002855- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2856 considering it exactly like a '*'.
2857
Walter Dörwald007f8df2005-10-09 19:42:27 +00002858- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2859 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002860
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002861- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2862
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002863- Patch #1413711: Certain patterns of differences were making difflib
2864 touch the recursion limit.
2865
Walter Dörwald58917a62006-03-31 15:26:22 +00002866- Bug #947906: An object oriented interface has been added to the calendar
2867 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002868 called as a script (e.g. via ``python -mcalendar``). Localized month and
2869 weekday names can be ouput (even if an exotic encoding is used) using
2870 special classes that use unicode.

2873-----
2874
Neal Norwitz602d3392006-03-31 08:21:40 +00002875- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2876 by using -mieee gcc option.
2877

2879
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002880- Build support for Win64-AMD64 was added.
2881
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002882- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2883
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002884- Patch #881820: look for openpty and forkpty also in libbsd.
2885
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002886- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2887 The zlib module is now builtin on Windows.
2888
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002889- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2890
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002891- Bug #1189330: configure did not correctly determine the necessary
2892 value of LINKCC if python was built with GCC 4.0.
2893
Trent Mick8321b422005-07-26 02:29:21 +00002894- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2895 vulnerability in zlib 1.2.1 and 1.2.2.
2896
Brett Cannon08cd5982005-04-24 22:26:38 +00002897- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2898 flags that change binary compatibility. Changes were also made to
2899 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002900 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002901
Bob Ippolitoed233462005-03-29 13:47:59 +00002902- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2903 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2904 no longer exists). This configure patch makes things right.
2905
Martin v. Löwise2713be2005-03-08 15:03:08 +00002906- Bug #1158607: Build with --disable-unicode again.
2907
Brett Cannon46d96232005-02-16 00:07:19 +00002908- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2909 defined. Discovered as a result of not being able to build on OS X.
2910
Brett Cannon516592f2004-12-07 00:42:59 +00002911- setup.py now uses the directories specified in LDFLAGS using the -L option
2912 and in CPPFLAGS using the -I option for adding library and include
2913 directories, respectively, for compiling extension modules against. This has
2914 led to the core being compiled using the values in CPPFLAGS. It also removes
2915 the need for the special-casing of both DarwinPorts and Fink for darwin since
2916 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2917 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2918 Fink, ``-I/opt/local/include`` for DarwinPorts).
2919
Brett Cannon43802422005-02-10 20:48:03 +00002920- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2921 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2922 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2923 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002925C API
2926-----
2927
Tim Petersc9d78aa2006-03-26 23:27:58 +00002928- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2929 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2930 is obtained via the ``PyObject_`` family, it must be released via the
2931 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2932 always been officially true, but when Python's small-object allocator was
2933 introduced, an attempt was made to cater to a few extension modules
2934 discovered at the time that obtained memory via ``PyObject_New`` but
2935 released it via ``PyMem_DEL``. It's years later, and if such code still
2936 exists it will fail now (probably with segfaults, but calling wrong
2937 low-level memory management functions can yield many symptoms).
2938
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002939- Added a C API for set and frozenset objects.
2940

2942
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002943- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2944 mapping argument now. This string is used as a mapping table. Byte values
2945 greater than the length of the string and 0xFFFE are treated as undefined
2946 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002952- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002953
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002954- Patch #1276356: New resource "urlfetch" is implemented. This enables
2955 even impatient people to run tests that require remote files.
